I had periods on 24th December.Before that I've done protected Sex.And after 7 days of missing periods I consulted to a doctor cause in pregnancy kit no results was showing.Then did a urine pregnancy test from path lab.The result was also negative.Doctor told it maybe false negative report due to early test.I don't want to conceive now.So she prescribed me Modus 10. Is it possible to remain pregnant after taking Modus?
